To ellylwm it may concern:

Be it known that I, Jonalt Prraa Hanan: Loan, citizen of Australia, residing at. The Waterworks, Rockhampton, in the Statepf Queensland, Australia, engineer, have mvented new and useful 1m rovements in Ruddera .for Controlling the arions Movements of Screw-lmpelled Vessels and Means for Operating Some, of which the following is a a itlcation.

This invention relates to an im roved conatruction of folding rudders an means for operating same by which the movements of screw propelled vessels, fitted therewith, are completelynmlcr the control of the helmeman or navi tor of such "9", and providing that t te ro llcr is revolvin at an effective speed m t to proper direction, he, the hrhnamanor navigator, can, from his place on the vessel, and without the main engines or motive power being in any way manipulated, cause the vesael to conform to any and all of the usual maneuvers of a norm propelled vessel, namely to go ahead at any desired speed, within the maximum, to stop, or'to I aatcm at a more or less nmderato rate 0 speed, and at the same tune to answer the helm in the usual manner. In addition, he can also turn the vessel in its own length, in either d rection and without any aubatantial forward or backward movement through the water. The vessel, is, therefore, under better and aurer control, especially tlt eonlinod waters; collisions are more easily IVOttlQtl; and, it desirable, the e! ine or motive power with the pro ller rigidly attached, may be started whi e the velaorl itself remains stationary and unaffected, although ready for any movement. which the hclmnman or navigator may delire to malts.

.My improved construction of folding rudder, provides the maximum ltrength with the minimum mill-sectional area and obatruction, the vertical oint in clean, and when the rudder in in o thor its neutral or go aatcrn 'tion, water cannot ones re aatern and Emmy its efllciency, wh ilo-. l te unmtruction of the operating device ts mmfile and effective, and it contains no features iuhlo to diaordcr. 'lho enginut in-u vowel titled with it, nut be of the simplest kind,

and conatructod or going ahead onl and, as the propeller is never disconnect or in any other way relieved of its resistance, (except, if desired, in sturtin throttling mechanism no in the case of engines not readily reversed, such as oil, gas, or turbine en ines, the usual reversing nr, disengu ing c utchcs, reversmg pro er ctc., may entirely dispensed with t crcby eli'ecting a saving in cost, whici will more than compensate for the additional cost. of installing my improved folding rudder and menus for operating it.

Brictly stated, my invention consists in an improvedconstruction of folding rudder and means for operating it, so that. it is enabled to deflect, retard or reverse the current of water sent nstern by the action of the propeller, whereby, in turn, the control of the vessel, as already described, is brought. about. 'llhis o ening, closing, and turntn of my iniprovct folding rudder is performed and controlled by the helnlsmun or mudgator from his usual position on the vessel, and is transmitted to the rudder by suitable mechanical means, either by hand power, steam, oil, gas. hydruulics, electricity, com- I air, or whichever motive power may )6 considered most suitable and convenient, according to the size and e| ui mn-nt and rcquirrlnents of the vrsecl. It runs are Ilitn provided whereby the relative position of the blades of the rudder may be indicated to the hrlmslnun or navigator.

In order that m invention may be clearly nnderntmxl, I wil now more tn ly describe it by the aid of thc m'rontpunying drawings in which my improvcd folding rudder an its uctunting mechanism is shown, as suit able for smull or modcruto sized vessels.

Figure 1 is a side elevation, art! in scction, the rudder being in its 0 user or go ahead position; Fig. 2 in n plan view of the same; Fig. 3 is a plnn showing the rudder opeucd upproximutoly to its neutral or stop" position; Fig. 4 is a (plan, partly broken nwuy, showing the ru der opened to its fullest uxtcnt or in the go aatet'tt ioeition; Fig. l: is at side elevation of a comiinrd stccrin and controlling device; Fi ti is on tlt!\ttllult of the rudder blades, with their rox mctivo shank and sleeve, or rudder houds, so ntrnted; and, Fig. 7 is 11 national phtn of t It! lilttdrs.

ltcfrrring to tho drawings, it. will be siren that the rudder is vertically tllVltlt'tl or split into two halves or blades A and li, which are pivoted on n common axle. Those the engines), no
